300 students attend Washington middle school.
Step-by-step explanation:
Given,
Percentage of students who play sport = 64%
Number of students who play sport = 192
Let,
x represent the total number of students at Washington middle school.
64% of x = 192
[tex]\frac{64}{100}x=192\\0.64x=192[/tex]
Dividing both sides by 0.64
[tex]\frac{0.64x}{0.64}=\frac{192}{0.64}\\x=300[/tex]
300 students attend Washington middle school.
